[Mailman-Users] how does Mailman store users

[R e i d O d a]

hi,

i'm thinking of integrating Mailman into a system which stores users in a
mysql database.  i'm wondering how Mailman stores users and if you have
any advice on how to make this happen smoothly.  i'd like for
subscribe/unsubscribe email messages also change the database.  

any advice would be greatly appreciated!
